cmpIdMapping

Description

Function to generate compound ID mappings UniChem.

This function requires the ID mapping files "src1src2.txt.gz", "src1src22.txt.gz", and "src1src7.txt.gz" to exist in a directory called "downloads" before being run. These can be generated with the downloadUniChem function.

It will do some processing on these files and output an RDS file at outfile. This file can then be used in other functions, such as drugTargetAnnot.

Usage

cmpIdMapping(outfile=file.path(config$resultsPath,"cmp_ids.rds"), rerun=TRUE,config=genConfig()) 
cmpIdMapping(outfile=file.path(config$resultsPath,"cmp_ids.rds"), rerun=TRUE,config=genConfig())

Arguments

`outfile`	Path to output file.
`rerun`	If true, runs processing, otherwise does nothing.
`config`	General configuration. See `genConfig`.

Value

Generates an RDS file at outfile.

Thomas Girke

Examples

	 
	 cmpIdMapping("cmp_ids.rds",rerun=FALSE)

getParalogs

Description

Using biomaRt, obtain for query genes the corresponding UniProt IDs as well as paralogs. Query genes can be Gene Names or ENSEMBL Gene IDs from H sapiens. The result is similar to IDMs and SSNNs from getUniprotIDs function, but instead of UNIREF clusters, biomaRt's paralogs are used to obtain SSNNs.

Usage

getParalogs(queryBy)
getParalogs(queryBy)

Arguments

queryBy

A list defining the query, as described in queryBy.

Value

Returns a list with the paralogs for the given genes.

Examples

	 queryBy <- list(molType="gene", idType="external_gene_name", ids=c("ZPBP", "MAPK1", "EGFR"))
	 
		 #requires network connection and is slow
		 result <- getParalogs(queryBy)
	 
queryBy <- list(molType="gene", idType="external_gene_name", ids=c("ZPBP", "MAPK1", "EGFR"))
	 
		 #requires network connection and is slow
		 result <- getParalogs(queryBy)

Gene to Protein ID Mappings

Description

The getSymEnsUp function returns for a query of gene or protein IDs a mapping table containing: ENSEMBL Gene IDs, Gene Names/Symbols, UniProt IDs and ENSEMBL Protein IDs. Subsequent slots contain the corresponding named character vectors. Internally, the function uses the ensembldb package.

Usage

getSymEnsUp(EnsDb = "EnsDb.Hsapiens.v86", ids, idtype)
getSymEnsUp(EnsDb = "EnsDb.Hsapiens.v86", ids, idtype)

Arguments

`EnsDb`	`EnsDb` instance of ensembldb package
`ids`	Character vector with IDs matching the type specified under `idtype`
`idtype`	Character vector of length one containing one of: `GENE_NAME`, `ENSEMBL_GENE_ID` or `UNIPROT_ID`

Value

List object with following components:

`idDF`	ID mapping `data.frame`
`ens_gene_id`	named character vector
`up_ens_id`	named character vector
`up_gene_id`	named character vector

Author(s)

Thomas Girke

Examples

	 gene_name <- c("CA7", "CFTR")
	 getSymEnsUp(EnsDb="EnsDb.Hsapiens.v86", ids=gene_name, idtype="GENE_NAME")
gene_name <- c("CA7", "CFTR")
	 getSymEnsUp(EnsDb="EnsDb.Hsapiens.v86", ids=gene_name, idtype="GENE_NAME")

Retrieve UniProt IDs via ID and Cluster Mappings

Description

The following returns for a set of query IDs (e.g. Ensembl gene IDs) the corresponding UniProt IDs based on two independent approaches: ID mappings (IDMs) and sequence similarity nearest neighbors (SSNNs) using UNIREF clusters. Note, the 'keys' or query IDs (e.g. ENSEMBL genes) can only be reliably maintained in the SSNN results when 'chunksize=1' since batch queries for protein clusters with 'UnitProt.ws' will often drop the query IDs. To address this, the query result contains an extra 'QueryID' column when 'chunksize=1', but not when it is set to a different value than 1.

The getParalogs function is similar but it uses biomaRt's paralogs instead of UNIREF clusters.

Usage

getUniprotIDs(taxId = 9606, kt = "ENSEMBL", keys, seq_cluster = "UNIREF90", chunksize=20)
getUniprotIDs(taxId = 9606, kt = "ENSEMBL", keys, seq_cluster = "UNIREF90", chunksize=20)

Arguments

`taxId`	An NCBI taxonomy ID
`kt`	Should be either "ENSEMBL" or "UNIPROTKB".
`keys`	Query IDs.
`seq_cluster`	Which cluster to use. Should be one of 'UNIREF100', 'UNIREF90', 'UNIREF50'.
`chunksize`	Queries are done in batches, this parameter sets the size of each batch.

Value

Returns a list of data.
